Abstract

Fossil diatom occurrence and anistropy of magnetic susceptibility are evaluated for their usefulness in differentiating glaclomarlne drift from till.

Fossil diatoms in Everson glaciomarine drift occur abundantly enough to be of paleoenvironmental significance only in association with in situ Serpula vermlcularia (Linne). Diatoms are generally a poor discriminator between till and glaciomarine drift. Paleoecological data suggest that, berg ice in marine water was the dominant agent of transportation for clastic particlesin Everson glaciomarine drift.

Anisotropy of magnetic susceptibility investigations generated a characteristic magnetic signature for each diamicton, demonstrating intrinsic differences in the petrofabrics of the two sediment types.
